GAS-MIXER.

Patented March 27, 1906.

Application filed October 26, 1905. Serial No 284.498.

To all whom it may concern.-

Be it knownthat I, MARCUS Soorr, a citizen of the United States, residing at J ackson the admixture with gas of atmosp erio air at a point relatively near the point-where the gas is roduced or generated, so as to provide an in ammable-gas compound which may be distributed through a service-pipe to individual burners without necessity for the further admixture of air at each individual burner, and thus providing a gas compound especially suited for heating purposes, the quality of which may be regulated by the addition to the gas of just the. proper proportion of atmospheric airat a central distributing-point, and thus dispensing with the necessity of mixing chambers or retorts at the individual burners.

The invention consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings have been illustrated simp e and preferred forms of the invention, it being understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations, and modifications within the scope of the invention may be made when desired.

.In the drawings, Figure "1 is a diagram illustrating the invention arranged for operation. Fig. 2 is a diagram illustrating a modification. Fig. 3 is a sectional detail view of the mixing-chamber. 1

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

M designates a, mixing-chamber which consists of a casing that has been illustrated in each case as being provided with three branches that are connected by suitable piping 1 and 2 with the sources of supply of gas and atmospheric air, res ectively, while the third branch is connecte with the distributing-pipe or service-pipe In Figs. 1. and 2 the air-sup ply is providedthrough the medium of a suitably-o erated blower 4.

In Fig. l of the rawings the blower is conreter on the other side.

nected with a carbureter C by means of a pipe 5, having a T 6 from which the air-supply pi e 2 extends to the mixing-chamber M, sai pipe 2 being provided with a valve 7, which may be a globe-valveof ordinary construction. The pipe 5 is also provided with globe-valves 8 and 9, disposed between the T and the blower on one side and the carbu- The hydrocarbon gas coming from the carbureter is conveyed to the pipe 1 through a pipe 10, having a valve 11. The'supply-pipe 1 has also been shown as being connected by a pipe 12, having a valve 13, with a gas-meter 14, which also constitutes a source of gas-sup 1y which may be either of natural or arti cial gas.

The service-pipe is provided at a point not far from the mixing-chamber with a valve 15, and said service-pipe also has a checkvalve 16 intermediate the valve 15 in the mixing-chamber. The gas or supply pipe has a check-valve 17 intermediate the mixing-chamber and the source of gas-supply.

The form of the invention illustrated in Fig. 1 is applicable to establishments that are provide with plants for generating hydrocarbon gas as by means of the carbureter shown in said figure. In Fig. 2 the gas is supplied only through a meter 14, and the carbureter being absent the blower is connected direct with the mixing-chamber by the pipe 2,

which has here been shown as provided with regulating-valves 7 and 8. In other respects theconstruction shown in Fig. 2 is identical with that shown in Fig. 1, and the same numerals have been employed to distinguish the several parts.

The construction of the mixing-chamber will be best understood byreferenceto Fig. 3 of the drawings, where it will be seen that the pipes 1 and 2 enter the opposite branches of the T, which constitutes the mixing-chamber, and extend past each other and past the inner end of the branch communicating with the servicepipe, terminating within the branches of the T opposite to those through which they enter. 'Thus the air entering through the pipe 2 and the gas entering through the pipe 1 will be compelled to move backto the common outlet through the lateral branchof the T, where a thorough admixture takes place.

In the several forms of the invention a thorough admixture of the mospheric air will take lace within the mixing-chamber, fi'om whic the mixture passes gas and the at-.

' into the service-pipe. The check-valves are arranged to regulate the passage of gas and air to the burners by automatically 0 ening Wider when additional burners are lghted and by automatically diminishing the size of the gas and air passage when burners are turned oil or extinguished, and the roportions of gas and atmospheric air enterlng into the mixing-chamber may be very accurately gaged or regulated according to the quality and nature of the gas by simply manipulating the valves upon the supply-pipes.

When, as in Fig. 1 of the drawings, the invention is applied to a plant including a gasgenerator, such as the carbureter C, the pipe 12, leading from the meter, may be normally closed by the valve 13, which latter will be opened only in the event of the failure of the carbureter or generator to provide the needed supply of gas when the valve 11 may be closed, as well as the valve 9 between the carbureter and the supply-pipe 2, which connects the mixing-chamber with the blower.

It is to be understood that the use of this invention is not limited to private establishments, manufactories, laundries, and the like where gas with an admixture of atmospheric air is to be supplied to a plurality of burners, but that said invention is equally applicable on a large scale at gas-manufacturing plants, where it may be desired to supply the gas with an admixture of atmospheric air previous to its being distributed through the mains.

Having thus described the invention,what is claimed is 1 A mixing-chamber having a branch con- 4 nected with a source of gas-supply, a branch connected with a source of air-supply, and a branch connected with a service-pipe; said gas and air supply pipes being extended into the mixin -chamber past each other and past the branc connected with the service-pipe; the several supplyipes and the service-plpe being provided wit 1 independent regulatingvalves, and the gas-supply )ipe and the service-pipe being provided with check-valves intermediate the regulating-valves and the mixing-chamber.

2. A mixing-chamber havin a branch connected with a plurality oi independent sources of gas-supply, a branch connected with a source of air-supply, and a branch connected with a service-pipe; the gas and air supply pipes being extended into the mixingchamber past each other and past the inner end of the branch connected with the servicepipe; the sources of gas-supply having independent valves controlling their connection with the mixing-chamber.

3. A mixing-chamber, sources of supply of gas and of atmospheric air connected with said mixing-chamber by means of pipes having regulating-valves, said pipes being extended into the mixing-chamber past each other; a valved service-pipe extending from the mixing-chamber, at a point intermediate the inner ends of the gas and air pipes; a check-valve in the service-pipe intermediate the regulating-valve and the mixing-chamber, and a foraminous diaphragm in the pipe adjacent to the check-valve.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two Witnesses.

MARCUS SCOTT.
